The gravitational force only acts btwn very massive objects

F

Doubling the distance between two objects halves the gravitational force between them.

F (1/4 Fgrav bc gmm/2r^2)

If object is placed 2 earth radii above earth, then 1/4 Fgrav

F (2 radii ABOVE earth, so 3 total = 3r^2 = 1/9 Fgrav)

Accel of g depends on mass of object

F (Wf = m*g- two separate things)

Incr mass of Object = incr g of Object?

F (changes Wf but not g)

Gravitational force btwn 2 objects is independent of smaller mass

F (dependent on both masses)

2x mass of earth and 2x radius = g still = 10 ish m/s ?

F (g= Gm/d^2- dist squared and m isnt- 2m/4r)

The gravitational force btwn an object and and the earth is inversely related to dist btwn object and earths center

F (inversely prop to dist squared)

If A attracts B with X newtons, B also attracts A with X Newtons

T

2x dist = decr g by factor of 4 ?

T (1/4 Fgrav)

Gravitational force acting on object is same as weight of object

T (Fgrav = Wf)

Gravitational force can Always be accurately calculated by mg

T (Fgrav = Wf)

Accel of g depends on mass of earth

T (accel DUE to gravity- Earth's pull)

Accel of g is inversely related to dist btwn the center of earth and center of object

T (ex: more dist = less g)

2x mass of earth (radius same tho), then g = 20 ish m/s ?

T (g = Gm/d^2)

Accel of orbiting object (constant speed) = accel of g at that particular location

T (idk why)

In both Copernican and Keplerian systems, the closer a planet is to the sun, the faster it moves

True
